WHY IS IT SO HARD TO CLOSE AN ACCOUNT?

I've been trying to close an account with RCS which has proven to be such a hassle! Ive called is multiple times and emailed the account closures department MULTIPLE TIMES yet my account is still open. I get different answers every single time I call in. First it would be closed in 48 hours, then it could only be closed at the end on an account billing cycle which is on the 12th of the month.. The 12th came and passed and now I'm being told it takes 36 days to close an account!! Unlike what you may think I read the terms and conditions before signing anything and your terminations clause states nothing about me having to wait 36 days to close an account! It's so easy to reel in clients to sign up but you have to make it a mission for me to back out? I have no outstanding balance in this account and I DON'T NEED IT ANYMORE! I want the account closed!
